When setting key-frames to an object’s Visibility or “restrict view-port visibility” property,
Its easy to forget that it doesn’t affect the visibility in rendering but only in the view-port display.
This gave me some really nasty glitches in production when rendered animation turned out different than what I had expected.
Simple solution to that is:
Whenever an object’s visibility needs to be animated,
First thing to do is to set a Driver for the “restrict rendering” property, that would be controlled by the “restrict view-port visibility” property.
That way the animation done on view-port visibility will automatically also control rendering visibility.
What’s needed is a simple single property driver which is very simple to setup and the huge headaches can be avoided that way.
